12. 12 Chair Steven Dunn Vice-Chair Wink Baker Secretary Dale Belter Chairs and Vice Chairs of Primary and Task SC’s Turbine Engine Testing WT Flow Quality Program Focus Groups Working Groups Primary SC Task SCs Dynamic Space Simulation Model Attitude & Deformation Dual Flow Reference Nozzle Design of Experiments Internal Balances Awards & Upgrades Publications Conferences Education & Student Activities Membership Steering Committee > Current Chair is active through Winter 2016 Meeting < Future of Ground Testing Measurement Uncertainty GTTC Organization

13. 13 Established to address technical needs in aerospace ground testing community Provide forum for discussion and the development of solutions and standardization Not a continuous activity - each working group identifies a specific goal or product that will be developed  Typically an AIAA Standard, Guide, Recommended Practice, or Special Project Report Anticipate each working group to exist for 4-10 years Must be chaired by GTTC member Membership includes both GTTC and non-GTTC and non-AIAA Meetings held to coincide with GTTC meetings “Lessons Learned” developed to provide “How To” guidelines for new working groups GTTC Working Groups

14. 14 Wind Tunnel Flow Quality  Chair: Ben Mills – AEDC/Aerospace Testing Alliance  Objectives: Develop best practices and/or standards on the measurement and reporting of unsteady or fluctuating flow parameters related to wind tunnel testing  Status: –Draft reviews –Finalizing document Model Attitude and Deformation  Chair: Bob Guyton – USAF/AFRL  Objectives: Develop a recommended practice AIAA document that discusses methods to measure model attitude and/or deformation in wind tunnel testing  Status: –Document taking shape –Updating draft write-ups GTTC Working Groups

15. 15 Internal Balance Technology  Chair: Ray Rhew – NASA Langley  Objectives: –Review the recommended math model or calibration matrix (6x96); Provide guidance/ formulas, on selecting the appropriate subset matrix –Investigate uncertainty estimate calculations to provide better estimates of the balance calibration uncertainty –Provide recommendations for thermal effects on balance performance. –Investigate and provide recommendations on how to include pressure effects. –Develop metrics for evaluating a balance’s condition. –Review the current axis system and determine if it is appropriate to shift to an international standard. –Provide recommendations on wind tunnel check loads.  Status: – Draft sections have been developed for 3 objectives GTTC Working Groups

16. 16 Dual Flow Reference Nozzle  Chair: David Myren – ASE FluiDyne  Objectives: Develop a recommended practice AIAA document for defining a “standard” configuration for dual flow reference nozzles –Dual Separate Flow –Dual Mixed Flow  Status: –Very active WG; regular telecom meetings between conferences –Work product in development GTTC Working Groups

17. 17 Measurement Uncertainty  Chair: Christi Pastor-Barsi – Sierra Lobo/NASA Glenn  Objectives: Assess and evaluate AIAA G-045-2003 and AIAA S-071A-1999 to determine if they need to be modified to align more with current national and international standards (ASME and ISO), pertaining to wind tunnel measurement uncertainty.  Status: First full meeting in January 2015; excellent membership; discussed background, technical needs, goals, actions GTTC Working Groups

18. 18 Future of Ground Testing  Chair: Steven Dunn – Jacobs/NASA Langley  Issue: There is a need to define the integrated S&T and DT&E capabilities required to support the nation’s needs through/beyond the year 2030 and to ensure that national stakeholders and decision makers understand how this works and why it is important.  Objectives: –WG team to develop GT meta-analysis based on major publications assessing the GT environment; product will be one or more conference papers. –In parallel, assemble joint team to organize the approach for producing an assessment report of integrated EFD and CFD requirements and recommendations across the RDT&E life cycle. –AIAA cross-cutting team to develop information advocacy briefing for non-engineers based on foundational info from the integrated assessment report  Status: –GT meta-analysis and document/writing ongoing –Developed initial framework for integrated EFD/CFD assessment GTTC Working Groups
